Quick answer

A first mortgage business loan is a business-purpose loan registered as the main, first-ranking mortgage over a property. It's often used to pay out an existing mortgage and release extra equity in one step, or to borrow against a property that has no mortgage. Because the lender ranks first, it's the structure that can support the largest amounts, up to $5m.

Key points

  • The lender holds first-ranking security over the property.
  • Often used to refinance an existing loan and release equity at the same time.
  • Suits debt-free properties and larger amounts up to $5m.
  • Involves a valuation, legal documents and paying out any current mortgage.

“First” is the important word here. When a lender holds the first mortgage over a property, it’s first in line if the property ever has to be sold to repay debts. That position is the strongest security a property lender can have — and it’s why first mortgage business loans can stretch to the largest amounts.

What is a first mortgage business loan?

It’s a business-purpose loan secured by a mortgage that ranks first on the property’s title. The property might be your home, an investment property, or the commercial premises your business operates from. The money, though, is for the business: growth, an acquisition, paying out expensive debts, funding a big project, or clearing a tax bill.

There are two common situations:

  1. The property has no mortgage. The new business loan simply becomes the first mortgage.
  2. The property already has a mortgage. The new loan pays out the existing lender and becomes the new first mortgage, often releasing extra equity in the same transaction.

If you want to keep your current home loan untouched, that’s what a second mortgage business loan is for.

Who is a first mortgage business loan good for?

  • Owners with debt-free or lightly geared property who want to put that equity to work for the business.
  • Businesses consolidating several debts — car loans, equipment loans, a tax debt, an expensive short-term loan — into one facility. See business debt consolidation.
  • Bigger projects: buying a competitor, a second site, a major fit-out or a large equipment upgrade.
  • Owners whose existing lender won’t increase their loan for a business purpose, but who have the equity to support it elsewhere.

How does it work, step by step?

  1. Tell us the plan. Purpose, amount, the property’s address and any existing mortgage balance. No credit check to enquire.
  2. Rough equity check. Estimated value minus existing debt gives the available equity, expressed as an LVR.
  3. Structure discussion. We look at term, repayment style (for example interest-only versus principal and interest) and how the loan will ultimately be repaid.
  4. Indicative offer and valuation. A formal valuation confirms the security.
  5. Payout figure. If there’s an existing mortgage, a payout figure is requested from that lender.
  6. Documents and settlement. Loan and mortgage documents are signed, the old mortgage is discharged and the new one registered. Surplus funds go to the business purpose.

Our guide to repayment structures explains the difference between interest-only, principal and interest, and balloon arrangements if you’d like to compare.

What are the pros and cons?

ProsCons
Strongest security position, so the largest amounts are possibleReplaces any existing first mortgage
Can refinance and release equity in a single stepMore legal work than a second mortgage
Suits consolidating several debts into oneDischarge and settlement costs from the old lender
Longer terms are possibleProperty is at risk if the loan isn’t repaid
Credit history weighs less with strong equityEvery property owner must sign

A first mortgage is a big decision, and it’s worth asking someone who’ll tell you whether a smaller second mortgage or an unsecured option would do the job instead. If you want that sanity check, send us the details.

What does a first mortgage refinance look like? (illustrative)

Imagine a landscaping business owner whose home is worth around $1.3m with $350k left on the home loan. Over the years the business has collected an equipment loan, a short-term loan taken in a hurry and an ATO payment plan — three repayments, three due dates and one tired owner.

A first mortgage business loan could pay out the home loan and the three business debts at settlement, leaving one facility with one repayment. Spare equity might also fund the new tipper truck that’s been on the wish list. The family still lives in the house; the difference is that the lender holding the first mortgage is now a business lender, and the debts are organised around the business’s cash flow rather than scattered across the calendar.

The catch: consolidating spreads short-term debts over a longer term, which can mean paying more in total. That trade-off is worth discussing openly before you commit — the aim is breathing room, not a bigger pile. The figures here are illustrative only.

What documents are needed?

  • Photo ID for borrowers, guarantors and property owners
  • ABN or ACN
  • Rates notice or title details for the property
  • Current mortgage statement (if there’s an existing loan) so a payout figure can be ordered
  • Business bank statements and, for larger amounts, BAS or financial statements
  • Details of any debts being paid out as part of the loan

What are the alternatives?

Ready to put that equity to work?

A property with plenty of equity is one of the most powerful tools a business owner has. Used carefully, a first mortgage business loan can replace a tangle of debts with one clear repayment, or fund the growth step that’s been on the whiteboard for years.

Frequently asked questions

What's the difference between a first and second mortgage business loan?

A first mortgage is the primary loan registered on a property title. A second mortgage sits behind an existing first mortgage. If a property is sold to repay debts, the first mortgagee is paid before the second, which is why first mortgages can usually support larger amounts.

Can I use a first mortgage business loan if my property has no mortgage?

Yes. A property that's owned outright is ideal for a first mortgage business loan, because the full equity is available as security.

Will a first mortgage business loan replace my home loan?

If your property already has a mortgage, a first mortgage business loan normally pays it out and becomes the new first mortgage. If you'd rather keep your existing home loan, a second mortgage is the usual alternative.

Is a first mortgage business loan a home loan?

No. The security might be a home, but the money is borrowed for a business purpose — for example expansion, buying a business or clearing business debts — and it's assessed as business lending.
